Battle strategy
The Ultima Weapon starts each battle by casting and Spread Laser, leaving everyone with a  count of 1.

Because The Ultima Weapon is permanently, and , normal  attacks will have no effect. Even Ultimate attacks like Lightning's Army of One have no effect. Breakers should instead concentrate on status effects, such as or.

(* It is possible to affect The Ultima Weapon's break gauge, but it requires dispelling the enhanced boon.)

Laser attacks
Each time you get hit by The Ultima Weapon's Laser, the counter will rise.

Once the laser counter has risen above a set amount (4?), the next laser attack will deal a colossal amount of damage. You can decrease this counter by using Esuna or Life Element Drives. Note that a 's Life Element Drives will not decrease the laser counter for other party members.

Area attacks
The Ultima Weapon frequently attacks with an area effect of differing elements. Each attack is warned ahead of time, giving the players a chance to cast Element Drives for their protection.

Summon Guardian
When the Ultima Weapon hits 50% health, it auto-casts, stopping all attacks for the rest of the turn. On its next turn, it casts Summon Guardian, which summons a Radiant Bomb and a Gloom Bomb. While these two guardians are present, Ultima Weapon also has, which turns all damage to Ultima into healing. (This boon drops as soon as both Guardians are dead.)

The Guardians will last for one turn, then self-destruct with typically heavy damage.

The final shot
When the Ultima Weapon hits 1 health left, it again gains. It spends its last turn casting Ultima on the party, then dies. A death at this point won't affect the outcome of the battle, but it will prevent your "no deaths" bonus on higher difficulties.

These are tradable in the multiplayer Item Exchange for various limited-time items, including weapons, skillseeds, and s. One week after the event ends, these components will expire and will automatically switch for components from other Light-based Sicariuses.
